Introduction
The MC68HC908MR24 is a member of the low-cost, high-performance M68HC08 Family of 8-bit microcontroller units (MCUs). The M68HC08 Family is based on the customer-specified integrated circuit (CSIC) design strategy. All MCUs in the family use the enhanced M68HC08 central processor unit (CPU08) and are available with a variety of modules, memory sizes and types, and package types.
Features
Features of the MC68HC908MR24 include:
• High-performance M68HC08 architecture
• Fully upward-compatible object code with M6805, M146805, and M68HC05 Families
• 8-MHz internal bus frequency
• 24 Kbytes of on-chip electrically erasable in-circuit programmable read-only memory (FLASH)
• On-chip programming firmware for use with host personal computer
• FLASH data security1
• 768 bytes of on-chip random-access memory (RAM)
• 12-bit, 6-channel center-aligned or edge-aligned pulse-width modulator (PWMMC)
• Serial peripheral interface module (SPI)
• Serial communications interface module (SCI)
• 16-bit, 4-channel timer interface module (TIMA)
• 16-bit, 2-channel timer interface module (TIMB)
• Clock generator module (CGM)
• Low-voltage inhibit (LVI) module with software selectable trip points
• 10-bit, 10-channel analog-to-digital converter (ADC)
• System protection features:
– Optional computer operating properly (COP) reset
– Low-voltage detection with optional reset
– Illegal opcode detection with optional reset
– Illegal address detection with optional reset
– Fault detection with optional PWM disabling
• 64-pin plastic quad flat pack (QFP)
• 56-pin shrink dual in-line package (SDIP)
• Low-power design (fully static with wait mode)
• Master reset pin (RST) and power-on reset (POR)
Features of the CPU08 include:
• Enhanced HC05 programming model
• Extensive loop control functions
• 16 addressing modes (eight more than the HC05)
• 16-bit index register and stack pointer
• Memory-to-memory data transfers
• Fast 8 × 8 multiply instruction
• Fast 16/8 divide instruction
• Binary-coded decimal (BCD) instructions
• Optimization for controller applications
• C language support
